Sight Words make up about 50 percent of regular English text. To become a great reader, a child must learn to automatically recognize Sight Words. Reading without this essential skill is as slow and frustrating as driving a car with a flat tire. Introducing Sight Words Sentence Builder—a proven learning tool for young readers. This kid-friendly app trains children to quickly recognize all Dolch Sight Words and build sentences from them. The Sentence Builder is not a mindless game that will be thrown out once all levels have been finished. The app can be played over and over until you see no more "blind spots" in your child’s Sight Words collection. Each level contains simple, common phrases that are constructed using Sight Words. As children hear each phrase, they must arrange words in the correct order to progress through the game. In other words, the app teaches Sight Words by "doing" rather than "viewing," which makes a world of difference! The key advantage of Sight Words Sentence Builder is that the game is interactive and quite exciting. Colorful graphics along with lovable animals and other "rewards" keep children curious and engaged, motivating them to keep improving. You can monitor your child’s progress on a report card, which shows recent scores and times played. With this information, you will know how your children are doing without standing behind them. Help your child learn a vital life skill. Start by downloading Sight Words Sentence Builder today!
